# etherunit
Etherium unit conversation and arithmetic library

## Usage

```python
>>> from etherunit import Ether, Gwei, Wei, E
>>>
>>> # Create a new quantity with units
>>>
>>> ## You can create a new quatity like this
>>> Ether(".05")
0.05 ether
>>> Gwei(".05")
0.05 gwei
>>> Wei("5")
5 wei
>>>
>>> ## Or you can use the helper function E() to create a new quantity
>>> E(".05 eth")
0.05 ether
>>> E(".05 gwei")
0.05 gwei
>>> E("5 wei")
5 wei
>>>
>>> # Arithmetic operations
>>>
>>> ## Different quatities can be added together without any problems
>>> E(".05 eth") + E("2 gwei") == E("0.050000002 eth")
True
>>>
>>> ## This also applies for subtraction
>>> E(".05 eth") - E("2 gwei") == E("0.049999998 eth")
True
>>>
>>> ## You can also multiply quanities with other integers
>>> E(".05 eth") * 2
0.1 ether
>>>
>>> ## ... but not with other quatities
>>> try:
...     E(".05 eth") * E("2 gwei")  # type: ignore
... except AssertionError as e:
...     print("Error:", e)
...
Error: 2 gwei is not an integer
>>> ## You also can't multiply quatities with other integers, like floats
>>> ## Why? Because it can result with fractional wei, which is not allowed
>>> try:
...     E(".05 eth") * 1.5  # type: ignore
... except AssertionError as e:
...     print("Error:", e)
...
Error: 1.5 is not an integer
>>> ## You can divide quatities with other integers, the result is always a quatity
>>> E(".05 eth") / 2
0.025 ether
>>>
>>> ## And you can divide quatities with other quatities, the result is always an integer
>>> E("10 eth") / E("3 eth")
3
>>>
>>> ## You can find the remainder of a division wiht %
>>> E("10 eth") % E("3 eth")
1 ether
>>>
>>> ## You can also use divmod() to get both the quotient and the remainder
>>> divmod(E("10 eth"), E("3 eth"))
(3, 1 ether)
>>>
>>> # Conversion
>>> ## You can convert a quatity to another quatity, though it's not necessary for arithmetic operations
>>> E("10 eth").gwei
10000000000 gwei
>>> E("10 eth").wei
10000000000000000000 wei
>>> (E("10 eth") % E("3 eth")).wei
1000000000000000000 wei
>>> E("10 eth").wei.eth.eth.eth.eth.gwei.wei.wei.wei  # :D
10000000000000000000 wei
```
